We use apt to download and install security updates on our production server, and most of the time this works well for us. However, this morning, our server downloaded an update, installed the updates, and then restarted one of the services being updated. This service requires a manual input on restart - and apt cannot supply said input. This effectively knocked out our server for a brief period (only a few minutes, but still).
What I'd like to know - is there a way to get apt to download the update, but notify via email that there is an update rather than simply install and restart services?
It would be great if we could do this per service - but there aren't a high volume of security updates (looking at the logs) so that's not a deal-breaker.
